High-efficiency shallow-water thruster

The thrust and propulsion efficiency of the Schottel Pump Jet type SPJ 30 has been further enhanced by CFD optimisations.

“Since the Pump Jet is installed flush with the hull of the vessel, the vessel’s resistance is not increased and the risk of collisions with flotsam is enormously reduced. Further protection against damage is provided by the protective grille on the inlet,” said Schottel.

“The robust SPJ is thus predestined for operation in extremely shallow waters – even in the event of grounding, the risk of damage is considerably reduced. The thruster is optionally available with elastic mounting, which further reduces noise levels and vibrations,” it added.

Due to the compact design of the SPJ 30, space-saving installation is possible with minimal displacement loss. The thruster is also extremely versatile: the above-water gearboxes are available as Z and L variants, and diesel engines, electric or hydraulic motors can be used as power sources.

SPJ 30 is suitable for a wide range of different vessel types, such as passenger vessels, ferries, work vessels and freighters. It can be fitted to both newbuilds and vessels undergoing modernisation.

The SPJ power range is from 50 to 3500kW. It can supply full thrust at a minimum immersion of 150 to 750 mm (depending on the specific model).
